I am amazed. First of all Columbine is I think my favorite flower (besides roses). I didn't know it had such a long range! Nor about the Iris's Jerry! I guess we are blessed with a real and long spring here Susan, but we share a love for similar plants. I like the windflowers too but I haven't had any problem with them getting out of control. I did with pinks some years back and this is the first year I am trying them again. I think the Scots call them "Bloody Bills", I may be wrong on that one but I don't hardly think so. Anyway, I am again surprised that my threads even got an answer. I thank you all, Alice too. I know I didn't mention your name but I saw your answer and I appreciate it. If I talk too much Joe is going to get a restraining order on me.
